Bruce Springsteen's cousin and assistant road manager was found dead in the Kansas City's Intercontinental Hotel Monday, not long before Springsteen and his band were to take to the stage.
"Lenny Sullivan, Bruce's cousin and the assistant road manager of the E Street Band for the last 10 years, passed away today at the age of 36," a statement on Springsteen's Web site
read. "A warm and sensitive person, he was beloved by Bruce, the Band, the crew, and the entire Thrill Hill family."
The death caused the cancellation of the show that night in Kansas City, Mo., with all tickets refunded and promises to return to the area "at the earliest opportunity."
Kansas City police said they are investigating, but that the death wasn't considered suspicious.
It's been a tough year for Springsteen, 59, who was accused of adultery
in a friend's divorce proceedings in the spring, and whose wife, Patti Scialfa, suffered a riding accident
in April. Last year, the E Street Band's longtime keyboardist
, Danny Federici, died at age 58.
Springsteen's next scheduled appearance is at Madison Square Garden Thursday for the Rock and Roll Hall of Fame concert.
